Age at Which Hair Loss Stops?

Hairloss can start as early as 16 (average 18) Around 35 years old in men there is a slow down of hair loss after 35 years old. But in geriatric years, you may continue to lose hair.

Thank you for your question.
Normally, hair loss starts between the ages 18-25
in most men. When a man passes his 35-40 age, hair loss usually slows down and
after the age of between 50-60, it increases again. This information shows us
that the process of hair loss is progressive and throughout life.
But there are always exceptions to the rule.That's
why It is always more efficient to have a medical examination.
But hair transplantation is permanent and always offers
successful solutions.

Hair loss stops when all the hairs are gone if you are a Norwood 6 or 7.  Only the hairs on the back of the head and over the ears remain.  This happens mostly in your 20s and 30s.  There are always exceptions to the rule.  Other Norwood class hair loss also happen in your 20s and 30s.  

There is no universal age at which hair loss stops. The amount and rate of thinning depends on a number of factors, such as environment, diet, general health, and especially genetics. Looking to your family history of hair loss is the best way to determine how much hair you’ll lose, when it will start, and when it will stop. This information will then tell you if a hair transplant is worth your while and if you’re likely to need a second one later on.

Hair loss for those who have it will continue until you die. If you look at actors who have not had hair replacement you can see that the pattern keeps expanding as they age and this has been my 35 year experience as well.
